This world is designed to favor the elderly. Gaining experience through trial and error first means that you have a competitive advantage over latecomers. It also occupies an advantageous position in social organization. This is the advantage that arises from being the first to start. However, the statement that 1 plus 1 equals 2 can be understood without any experience; it serves as an analytic proposition that can be known by reason compared to the aforementioned experiential proposition. In other words, in the realm of analytic propositions, the advantage of being older does not hold much weight. The world needs both experiential propositions and analytic propositions, but experience is not always essential. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
